They say “embedding.” You get an iframe. Three iframes later, your page crawls. Your security team panics. Pyramid gives you native code — React, Angular, JS — not workarounds. Feels like part of your app because it is. If it’s still iframe-based, it’s not modern BI. #PyramidAnalytics #BusinessIntelligence #AI #EmbeddedAnalytics

They often say “Don’t just jump to new frameworks.” That’s true — but I also believe in exploring new tools with purpose. Every framework or library has its strengths and trade-offs. The goal is to find the one that fits your style, workflow, and project needs — then master it. Over the past few weeks, I’ve been exploring TanStack Router, and honestly, it’s been a refreshing experience. For me, it feels like a solid replacement — or even an upgrade — to React Router in several ways. Here’s what stands out for me: - 🔒 Type-safe by design – it integrates beautifully with TypeScript, catching route-related errors early. - 📁 File-based routing – intuitive and scalable, similar to what you’d find in Next.js. - 🔄 Seamless integration with TanStack Query (React Query) – data fetching and routing now feel like one unified experience. - ⚙️ Declarative and framework-level flexibility – TanStack Router can serve as a mini full-stack framework for building entire React apps. - 🚀 Performance-focused – built with modern React patterns, offering faster navigation and smarter data loading. For now, I’m sticking with the router approach, but I’ll definitely be using both React Router and TanStack Router, depending on the project requirements. 👉 My little advice: explore new frameworks with intention. Don’t just jump straight into tutorials — start with the official docs. If you get stuck, Google it or ask AI tools for clarity. Only then should you watch tutorials to see practical applications. You’ll understand the “why” behind the “how,” and that makes all the difference. #ReactJS #TanStackRouter #WebDevelopment #Frontend #ReactQuery #DeveloperTips #TypeScript #LearningJourney

🚀 The Node.js Event Loop (JavaScript) The event loop is the heart of Node.js's asynchronous, non-blocking architecture. It continuously monitors the call stack and the task queue. When the call stack is empty, the event loop picks up the first event from the task queue and pushes it onto the call stack for execution. This allows Node.js to handle multiple operations concurrently without blocking the main thread, making it efficient for I/O-bound tasks. Understanding the event loop is crucial for writing performant Node.js applications. 👉 Learn smarter — 10,000+ concise concepts, 4,000+ articles, and 12,000+ topic-wise quiz questions, personalized by AI.

🚨 Why is my API call running again and again? This happened to me recently while working on a React dashboard. I had a simple useEffect that fetched user data when the component mounted: useEffect(() => { fetchUserData(); }, [user]); Looked innocent, right? But every time something updated in the app — this effect ran again, triggering multiple API calls. At first, I thought React was just being React 😅 But the real issue was deeper. 🧠 What was happening? user came from Context, and React treats object references as new on every render — even if the object’s content didn’t change. So, each render → new reference → effect re-runs → API storm 🌪️ ✅ The Fix Instead of passing the entire object, depend only on what’s necessary: useEffect(() => { fetchUserData(); }, [user.id]); // primitive, stable dependency Or, if you truly need the object, memoize it using useMemo or ensure the context value is stable. 💡 Takeaway > React compares dependencies by reference, not by value. Objects, arrays, and functions can silently trigger re-renders if not memoized. 🗣️ Your Turn Have you ever been bitten by dependency arrays or re-renders in React? How do you handle it — memoization, state refactoring, or something else? #ReactJS #JavaScript #WebDevelopment #ReactHooks #FrontendDevelopment #CodeTips #ReactPerformance #Nextjs #DevCommunity

🚀 Zod vs Joi vs Validator.js — Which One Should You Use? In modern web development, data validation is non-negotiable. Whether you're handling user input on the frontend or securing APIs on the backend — a solid validation library keeps your app safe and your data clean. Let’s quickly break down three popular libraries 👇 🧩 1️⃣ Zod Written in TypeScript — perfect type inference! Validation + schema definition in one place Excellent for frontend frameworks like React, Next.js, and tRPC Lightweight and developer-friendly ✅ Best for: TypeScript projects & full-stack apps using Next.js or tRPC ⚙️ 2️⃣ Joi Mature and battle-tested by the Node.js community Powerful schema syntax and great for complex backend logic Rich plugin ecosystem Slightly heavier and not TypeScript-first ✅ Best for: Backend (Node.js, Express, Hapi) applications 🧮 3️⃣ Validator.js Focused on string validation (emails, URLs, UUIDs, etc.) No schema system — you manually call functions Extremely lightweight ✅ Best for: Simple validations or when you only need quick field checks ⚔️ So which one wins? 💡 If you're building a TypeScript-based full-stack app → go with Zod. 💡 If your project is a backend API without TS → Joi fits perfectly. 💡 If you just need quick, simple field validation → Validator.js is all you need. 📣 My pick: Zod — it’s modern, TypeScript-friendly, and keeps your validation and types in perfect sync. What about you? Which validation library do you prefer — and why? 🤔 #WebDevelopment #JavaScript #TypeScript #NodeJS #React #Backend #Frontend #Zod #Joi #Validatorjs

🚀 Next.js 16 is here — and it’s a big one. This release brings some major improvements to performance, developer experience, and AI tooling. Here are the highlights 👇 🔥 What’s new - Cache components: More explicit caching for pages, components, and functions — fine-grained and predictable. - Next.js DevTools MCP: A game-changer for AI agents — provides contextual insights and debugging via the Model Context Protocol. - proxy.ts: Replaces middleware.ts. Same behavior, just a clearer name. Turbopack (stable): Now the default bundler — 2–5× faster production builds. - React Compiler (stable): Built-in automatic memoization. Zero effort, huge perf gains. - React 19.2 support: Adds View Transitions, useEffectEvent, and new Activity APIs. - Better routing & prefetching: Faster page transitions, smoother UX. Separate dev/build outputs: Finally solves those annoying build conflicts with AI coding agents. ⚠️ Breaking changes next lint is gone (linting no longer part of the build step). middleware.ts → renamed to proxy.ts. 💡 Pro tip: Give it a week or two before upgrading — patch versions usually follow fast. Next.js just keeps pushing the edge of what’s possible for modern web apps. #Nextjs #React #WebDevelopment #JavaScript #DevTools

The more I learn about JavaScript and modern frameworks like React and Next.js, the more I realize how fast the developer world is changing. A few years ago, the main focus for web developers was responsive design and smooth UI interactions. But today, we’re stepping into a new phase, one where AI becomes part of the web experience itself. Imagine logging into a web app that adapts to your behaviour, gives personalized recommendations, or answers questions instantly using an AI model. That’s not science fiction anymore. It’s what’s being built right now with AI APIs, React, and Next.js. The next generation of developers won’t just build websites. They’ll build intelligent web systems. #JavaScript #React #Nextjs #AI #WebDevelopment #LearningInPublic

🇺🇸 🎮 I've decided to make my "next_game" project public! 🎮 Years ago, I developed a complete mobile app in React Native, supported by a modular Node.js/Express backend—with JWT authentication, image manipulation, Firebase Admin SDK integration, and its own intelligent recommendation system. Besides being my graduation thesis at the Federal Institute of Education, the project's unique feature lies in the integration and automation of video game recommendations among different users. 🎮 Integration with the IGDB API https://www.igdb.com/api The backend connects to an external API called IGDB, which is responsible for providing detailed game information—such as title, genre, studio, image, and original synopsis (in English). This data is processed, normalized, and stored in Firebase. During the workflow, I implemented a machine translation layer using the Google Translation API (via the free-translate package), which converts all synopses into Portuguese. The result is a multilingual database updated in real time—fully automated and ready for consumption by the app. 🧠 Personalized Recommendation Engine On the backend, I developed my own recommendation system that: - Analyzes user preferences, genres, and behaviors. - Prioritizes recommendations from followed authors. - Deduplicates and ranks games by relevance, affinity, and reputation. - Persists personalized recommendations in Firebase. All this without external machine learning dependencies (it was developed in 2022)—just pure logic, heuristics, and dynamic rules. ⚙️ Technical Stack Backend: Node.js, Express, Firebase Admin, Passport-JWT, Jimp, Canvas, Moment, Free-Translate, Consign Frontend: React Native, React Navigation, React Native Elements, Encrypted Storage, Vision Camera 🔒 Architectural Best Practices - Sensitive configurations isolated in .env - Backend decoupled into routes, controllers, and services. - Asynchronous pipelines for integration with external APIs. - Modular, clean, and scalable structure. 🚀 Next Steps: - Adopt TypeScript across the stack. - Add automated testing and CI/CD with GitHub Actions - Document endpoints and architecture. https://lnkd.in/dmNmjC_P https://lnkd.in/dB6GajEV #frontend #backend #api #node #jwt #reactnative #react #rest #firebase
